By the described operation the inner and outer plates 9 and ll are notonly permanently interlocked with one another, but they are caused topress toward one another and, therefore, to grip the interveningdispensing plate 6.

'I'he arcuate edges i 5 of the aperture in the dis'- pensing plate 6cooperate to form a rotary bearing for engaging the ends of the boss I0.The side edges IG of the aperture formed in the plate 6 4serve to limitrotary movement of the closure device by engagement with the sides ofthe boss l0. The outer plate Il is desirably formed with an operatinghandle 22 whereby the closure device may be rotated. Rotation of theclosure device is effective to carry the openings i4 and Ma into and outof registry with the openings 'l of the dispensing plate 6. rIhe factthat the inner and outer plates 9 and li are pressed into grippingrelation with the plate i5 assures the provision of a double seal forthe dispensing plate, that is to say, the seal formed between thedispensing plate and the inner plate 9, and the seal formed between thedispensing plate and the outer plate i E.

The cap 3, with the closure device 8 aixed to it in the mannerdescribed, is threaded on the neck t of the can.

In the form of can disclosed in Figs. 6 and 7, provision is made of acan body 23 of any usual construction to which a cap 24 is aiiixed. Thecap comprises a dispensing plate 25 having a dispensing opening 28formed in it. Here again a closure device 2l is permanently assembledwith 'the cap 2d before the cap is affixed to thecan body 23. In thisinstance, the cap is illustrated as having a flange at its lower endwhich may be soldered to the can body, although any other suitable meansof attachment may be employed.

The closure device 2l comprises an inner imperforate plate 28 having ahollow boss 29 and an outer plate 3S which is imperforate save for thepresence of a boss fitting aperture which is surrounded by a shortupstanding flange 3 I. The relation of the boss Hl and the aperture ofthe plate 36, and the interlocking of the two plates, are all the sameas has been described with reference to the plates 9 and Il. The closuredevice is slidable bodily with reference to the dispensing plate 25, andis shown in both Figs. 6 and 7 as in the open position.

The inner plate 28 is formed with straight side edges 32 which serve asguiding edges cooperating with flat inclined side flangesI 33 formed onthe dispensing plate 25. The edges 32 and the flanges 33 cooperate toguide the closure device 2l to and fro in a straight path.` Thedispensing plate 25 is formed with a guide slot whose width is equal tothe major dimension of the boss 29. The Walls of the slot and the endsof the boss 29 cooperate in guiding the closure device in the desiredpath.

The outer plate 30 is made long enough to cover the dispensing plate 25from end to end. The inner plate 23 is substantially co-terminous withthe outer plate at its forward end and servesl to limit the movement ofthe closure member to a desired closed position.v The opposite end ofthe plate 28 terminates considerably short of the corresponding end ofthe plate 30 and serves to limit the movement of the closure device to adesired open position substantially as illustrated in Figs. 6 and 7.

.The plates 25, 28 and 30 are all desirably of curved form and are ofsubstantially equal curvature.

I'he plates 25, 28 and 30 are assembled with one another and united inthe manner illustrated in Figs. 4 and 5 and described in connection withthose gures. It will be understood, however, that where curved platesare employed as illus- .trated in Figs. 6 and 7, the plate engaging faceof opening therein, and the inner plate having an ovate boss whichextends outward through the dispensing plate and the ovate opening ofthe outer plate and which projects beyond the outer plate, theprojecting portion of said boss being formed with laterally extendingshoulder portions to overlie the outer plate.

2. A powder container as set forth in claim 1 in which the overhangingshoulder portions of the boss stress the closure plates toward oneanother and into gripping relation to the dispensing plate.

3. A powder container as set forth in claim 1 in which the outer plateis formed with a short upstanding flange for surrounding and fitting theboss and for engaging beneath the overhanging shoulder portions of theboss.

4. A powder container as set forth in claim l in which the dispensingplate is formed with a central opening having opposed arcuate edgeswhose diameter is equal to the major dimension of the boss, to provide arotary bearing for the boss.

5. A powder container as set forth in claim 1 in which the dispensingplate is formed with a parti-circular central opening whose ends formarcs of a circle having a diameter equal to the major dimension of theboss, to provide a rotary bearing for the boss, and with a series ofpowder discharging openings, and in which the inner and outer closureplates are formed with like series of powder openings in constantregistry with one another and adapted to be moved into and out ofregistry With the openings of the dispensing plate by rotation of theclosure device.

6. A powder container as set forth in claim 1 in which the dispensingplate is formed with a b'oss engaging guide slot, and with straightfaced guide flanges, the inner plate being formed with straightsideedges for cooperating with said guide flanges.

'7. A powder container as set forth in claim 1 in which the dispensingplate is formed with a boss engaging guide slot, and with straight facedguide anges, and with end anges for limiting movement of the closuredevice, the inner plate being formed with straight side edges forcooperating with the guide flanges of the dispensing plate, and beingsubstantially co-terminous with the outer plate at one end butterminating short of the outer plate at the other end, the long andshort ends of the inner plate serving respectively to limit movement ofthe closure device in closed and open positions.

8. A powder container as set forth in claim 1 in which the dispensingplate is formed With a `boss engaging guide slot, and with straightfaced guide flanges, the inner plate being formed With straight sideedges for cooperating with said guide flanges, the inner plate, theouter plate, and the dispensing plate being all curved lengthwise andbeing of substantially equal curvature.

9. A device adapted for dispensing powder comprising the combination ofa dispensing plate provided With an aperture having opposed arcuate endWalls, and a second aperture spaced from said first aperture, inner andouter plates having aligned openings therethrough adapted to registerwith said second aperture, said inner plate being provided with anintegrally formed hollow boss which extends through the dispensing plateand outer plate, and said boss having curved ends arranged to slidinglyengage the arcuate end Walls of the aperture in the dispensing plate,and means on said outer plate engaging said boss for preventing theouter plate from rotating with reference to the inner plate.

10. A device as set forth in claim 9 in which the means on the outerplate comprises an upturned flange formed integral with the outer plateand having its inner wall in engagement with the outer periphery of theboss.

11. A device adapted for dispensing powder comprising the combination ofa dispensing plate provided with an aperture and an opening spaced fromsaid aperture, inner and outer plates engaging the opposite faces ofsaid dispensing plate and having aligned openings therethrough adaptedto register with the opening in the dispensing plate, said inner platehaving an integrally'formed hollow boss extending upwardly through theaperture in the dispensing plate, the cross-section of said boss in aplane parallel to the dispensing plate being non-circular, means formedon said outer plate engaging the opposite `sides of said boss to preventrotation between said outer plate and said boss and a handle secured tosaid outer plate.
